Fred for Model Number Model SCB1001MSS 01 I had the wandering blinking display issue on my GE Advantium oven, which seems to be common. However, the common fix, the digitron board, did not work. I was confident, based on my google research, that this was the issue. Could I have purchased a defective new board? Or is something else the culprit? Display wanders, blinks/flashes. After a while it may settle down and display as stable time until the next time I use the microwave and it reverts to the wandering.
Answer Fred, with the power supply to the appliance off, the power transformer WB20X10021 for the user controls would need to be tested to ensure that it is within operational tolerance. At the relay control WB27X32849 connection CN1, the white wire and black wire tested together should measure 23.2 Ohms. At the power board WB27X10861 connection CN7, it should measure 1.5 Ohms from the yellow wire to the black wire, 5.2 Ohms from black wire to white wire, and 1.1 Ohms from the red wire to the brown wire. If this tests good, it would be likely that the main control WB27X10858 has failed. Read More... Answered by AppliancePartsPros.com | Wednesday, June 16, 2021
